of the upper housing 120, may be fastened to each other.
Accordingly, the locking groove 122 and the button portion 111 are
configured to be positioned so that the upper housing 120 is tilted
by the predetermined tilting angle, preventing noise from occurring
in the state in which the upper housing 120 is tilted.
[0080] Furthermore, when the locking groove 122 and the button
portion 111 are fastened to each other as the upper housing 120 is
tilted, vibration of the upper housing 120 may be prevented, and
fixing force to maintain the predetermined tilting angle is
provided.
[0081] Furthermore, according to an exemplary embodiment of the
present invention, when the upper housing 120 includes an elastic
member 113 providing the force to restore the upper housing 120
toward the lower housing 110 to be in the closed state, a coupling
structure of the locking groove 122 and the button portion 111 is
provided so that the upper housing 120 maintains a predetermined
angle.
[0082] According to an exemplary embodiment of the present
invention, the following effects may be obtained by the
configuration, coupling, and relationship in use described
above.
[0083] The present invention selectively provides rearview in
consideration of a driving environment of a user, increasing user
convenience.
[0084] Furthermore, when providing the rear view through the
display device, it is possible to provide a more clear rear view by
removing image overlay.
[0085] Furthermore, the OFF/OFF state of the display device is
selectively performed, reducing power consumption in a vehicle.
